install <file1 file2 | file1 ... fileN directory | directory ...>

The file(s) are copied to the target file or directory. If the destination is a directory, then the file is copied into directory with its original filename. If the target file already exists, it is either renamed to file.old if the -b option is given or overwritten if permissions allow. An alternate backup suffix may be specified via the -B option's argument


file1 file2 | file1 ... fileN directory | directory ...File(s) or directory(ies) installation directive


-B <suffix>Use suffix as the backup suffix if -b is given
-bBack up any existing files before overwriting them by renaming them to file.old. See -B for specifying a different backup suffix
-CCopy the file. If the target file already exists and the files are the same, then don't change the modification time of the target
-cCopy the file. This is actually the default. The -c option is only included for backwards compatibility
-dCreate directories. Missing parent directories are created as required
-fSpecify the target's file flags; see chflags(1) for a list of possible flags and their meanings
-gSpecify a group. A numeric GID is allowed
-MDisable all use of mmap(2)
-mSpecify an alternate mode. The default mode is set to rwxr-xr-x (0755). The specified mode may be either an octal or symbolic value; see chmod(1) for a description of possible mode values
-oSpecify an owner. A numeric UID is allowed
-pPreserve the modification time. Copy the file, as if the -C (compare and copy) option is specified, except if the target file doesn't already exist or is different, then preserve the modification time of the file
-SSafe copy. Normally, install unlinks an existing target before installing the new file. With the -S flag a temporary file is used and then renamed to be the target. The reason this is safer is that if the copy or rename fails, the existing target is left untouched
-sExec's the command strip(1) to strip binaries so that install can be portable over a large number of systems and binary types
-vCauses install to show when -C actually installs something
